COWMILKING DEVICE.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed May 21,1906. 8eria1No.318,028.

To ML whom it may concern:

Be it known that I,-MONROE HQDANIELS, a citizen of the United States, residing at Waverly, in the county of Bremer and State of Iowa, have invented certain new anduseful Im rovements in Cow-Milking Devices, of which the. following is a specification.

This invention relates to new and useful improvements in cow-milking devices, and pertains pprticularly to a type of construction in w ch a suction-bellows is provided, which carries a pi e or tube designed to have connection with t e udders of the animals in order to draw themilk therefrom.

In connection with an a paratus of the above type means are providbd for stopping the milking operation when the receptacle into which the milk: is discharged is filled to a predetermined degree or when the flow of milk ceases from the animal. Means are further rovided for regulating the sucl ion from the el'lows or pump, comprising a safetyvalve designed to be opened when the suction has reached a selected degree.

The detailed construction will appear in the course of the following description, in which'rcference is had to the accompanying drawings, forming a art of this specification, like numerals I esignating like parts throughout the several views, wherein- Figure 1 is a view illustral ing in side elevation a complete apparatus constructed in accordance with my lllVGIltIOll. Fig. 2 is a central longitudinal section illustrating'the detailed construction of the safety-valveforming a part of my invention. Fig. 3 is a fragmentary pers ective view of the top of the milk-receptac e, illustrating an automatic valve for stopping the operation of the pump when the flow ofmilk from the animal ceases; and Fig. 4 is a front elevation thereof.

In the practical embodiment of my invention I employ a suction-bellows 1, suspended by vertical hangers 2 from a suit able sup ort 3. The bellows 1 is positively operated T0111 a rod 4, fulcrumed, as at 5, to a sup )ortingpost 6 and formed at its free ends with corruations 7 and 8 on the respective upper and ower edges thereof. For the purpose of giv ing powerto the rod 4 a weight 9 is provided, which adjust-ably depends therefrom by a hook 10, designed to engagea selected one of i valve 41 of approved form, through which.

the air contained therein egrcsscs when the the corrugations 7. The rod 4 has connec- .tionwith the bottom of the bellows 1 by virtue of a loop 11, to which said rod is fulcrumed, as at 12. The bellows 1 has connect'ion at its to with a pipe 13, provided with a horizonta arm 14, which is engaged by hangers 15, depending from the support 3. The pipe 13 terminates in a dependmg arm 16, w iich adjacent to its extremity is provided with a hand-valve 17 and an auto matic safety-valve 18 for regulating the Ilow of air therethrough. The pipe 16 has con nection with a flexible tube 19, leading to a milk-pail 20, suspended from the )ipe 16 by a hook 21, engaging the bail 22' oi said pail. A pipe 23 leads from the ail 20 and terminines in a plurality of in es or mouths 24, which are secured to the uddcrs of the cow or other animal to be milked.

The above elements cOliSiitutG in general the main parts of the invention, which in performance-of their funct ions are provided with a number of devices to be hereinafterde scribed in detail and specifically referred to in the figures in which they are illusi rated.

The action of the bellows 1 under the influence of the weighted rod 4 is controlled by an escapement mechanism comprising a reel 25, transversely journaled in vertical brackets 26, carried upon the top of the bellows 1. The reel 25 carries at its end an escapement-wheel 27, removably secured thereon by a set-nut 28. The rod 4 has connection with the reel 25 by virtue of a cord 29, adjustably engaging at one end the corrugations 8 of said rod and being trained over a sheave 30, carried upon the top of the bellows 1, the other end of said cord engaging and being rigidly secured to the reel 25. For the purpose of cushioning the action of the rod 4 upon the reel, so as not to jar the same in its bearings, a spring 31 is interposed at a desired point in the cord 29. The action of the rod 4 is counterbalanced by weight 32, suspended from a cord 33. trained over a sheave 3-1, carried upon the top of the bellows 1,, and trained over the reel 25 in an opposite direction from the cord 29. The ratchet-wheel 27 is engaged by a double escapement-pawl 35, pivotallv mounted in a depending bracket 36, provided with a pendulum 37 0! approved form carrying an ad justable weight 58. The apparatus is started in its action by manually-operated men us. comprising a suitably-supported pullcord 13$), provided at its end with a handle The bellows 1 is provided with a checkbellowsis contracted.

The automatic safety-valve 18 is illustrated in dctail in Fig. 2 and comprises a cupshapcd member 42,1itted into the pipe 16 and lormcd in its exposed surface with air-inlet openings 43, which are normally closed by a reci|,)ro(.'aling disk valve 44, slidable within the annular wall ol the member 42 and carrying a stem -15, threaded into said valve ti and terminating in a milled head 46. An expansive coil-spring 47 sur rounds the stem 45 and imparts a tension tothe valve 4t in its action. The tension of the spring 47 is rcgulatcd by turning the threaded rod 45.

The flexible tube It) terminates in a floatvalvc -18 of any approved form, which is desi ned to be closed by the milk when it has reached a predctcrmincd height in the pail to cut oil' suction from the bellows 1. The valve 48 more strictly speaking, carried by a top 49, designed to be secured by clips 50 to the pail 20 in such a manner that an airtight joint is effected between said pail and said top it).

The pipe 33; has connection with the lid 49, which adjacent to said pipe is provided with an inwardi v-cxtcuding pipe-section 51. termiimting in a liqind-controlled valve 52 of novel con truction. designed to be closed when the milk ceases to flow from the udders of the animal and to stop the suction of the bellows i. The valve 52 comprises a disk or'a disk cap 52 as desired, rigidly secured to the pipe-section 51 and provided in its lower half withan opening A disk is pivotally connected to the disk 53 at a central point. as at 56. and is provided with an opening 57. adapted to be brought into rcgistr v with the opening 54 in the movement of the disk 55 upon its pivot. The movement of the disk 55 in either direction upon its pivot is controlled by a pin 58, rigidly carried by the disk 53 and projecting through an arc-shaped slot 59; formed in the disk 55. Said disk 55 carries a rigid element 60. terminating in a Vshaped extremity disposed adiacent to the opening 5? and design d to be engaged by the milk discharged through the openings 54 and 57 in their registering relation with a gravitating action. For the purpose of initially elieeting a registering relation between the openings 54 and 57 a stem 61 is pivoted to the face of the disk 55 and projects through the top 49, said stem carrying at its upper end an enlarged weighted head 62.

In operation the pull-cord 39 is grasped by the hau ilo 4t) anl moved to oscillate the peridulum 37. The oscillation of the pen iulum 37 releases thc oscapement-wheel 27, anl the weightel ro t4 acts by gravity to expan l the bellows i in a scrirs of vibratory mo'rcn'n nts as controlled by the cscapcmcnt-whcel 27 gal pawl 35. it is of course to be nutcrstooi that in the gravitating movement of the rod 4 upon its fulcrum the reel 25 is rotated, carrying the escapcmimt-u heel 27 therewith and winning the counterbalanceweight 32 upon said reel. As thc bellows expanus a suction uill be created from the various pipes herein set forth, u hereby the milk from the udders of the cow ill be orau 11 into the pail 2t) andfrom vihich it may be discharged by a drain-cock 63. Whenthe pail is filled to a predetermined limit, the floatvalve 48 is operated by the milk as it rises in sail pail to close the mouth of the tube It) and to stop the suction upon the udders of the cow. in starting the device the disk 55 is moved to the position of Mg. 4 by raising the stem 61 and is held manually in such position until the milk starts to llow, and the falling milk impinges upon the clcmcnt (it) with a gravitating action and maintains the valve 52 in the position of l ig. 4. When the milk ceases to How from the uddcrs of the cow, the weighted pin 61 drops by gravity and rocks the disk 55 upon its fulcrum 56, so as to move the opening 57 out of registry with the opening 54 and thcreby stop the suction upon the udders of the cow. .It will thus be seen that when the rod 4 has rcachcd the limit of its downward movement the u eight 32 will be wound upon the reel In restoring the bcllovi s to initial position the rod. 4 is lifted manually, and the weight 132 gravitatcs until the (UlRl 33 is unwound from the rcc 25. The pcndulum 37 assumes a perpcn'lieular position, so that movement of the cscapcment-u heel, the reel, and devices suspenied therefrom is prevented until the peniiulum is manually moved, as above set forth.

While the clemcnts herein shown and describe? arewcll a "aptetl to serve the functions set forth, it is obvious that various minor changes may be mare in the proportions, shape, and arrangement of the several parts ithout departing from the spirit and scope of the invention as defined in the appended claims.
